I've had a pea size lump under my right armpit since i can remember. However, as of late (Since December) it "flares" up, is swollen and painful. The lump is not on the outside of the skin, it's underneath. There's no head to it, it doesn't move. It's not an ingrown hair, I've switched deodorants. Nothing helps it.
Weird thing is, it only gets painful and swollen during ovulation and my period. Then it goes away completely until the next month. I was thinking a lymph node but I'm not sick at all.
I have an appointment next week with my PCP but my hypochondria is making me think I have breast cancer or some sort of hidden infection that is killing me slowly.
